In: Young, GB, Ropper, AH, Bolton, CF, (Eds), Coma and Impaired Consciousness, McGraw-Hill, 1998. Vale TC, Freitas Dda S, Maciel RO, et al. Dehydration also can lead to increases in total serum protein, albumin, amylase, and creatine phospho-kinase concentration in patients with acute diabetic decompensation. UpToDate allows you to search in the languages below. Delirium as a predictor of mortality in mechanically ventilated patients in the intensive care unit.

In: Grotta, J, (Ed), Management of the Acutely Ill Neurological Patient, Churchill Livingstone, New York 1993. Current opinions regarding the importance, diagnosis, and management of delirium in the intensive care unit: a survey of 912 healthcare professionals. Despite major advances in their management, recent series have reported a mortality rate of 2–5% for DKA, and ∼15% for HHS. Delirium in the intensive care unit: occurrence and clinical course in older patients. Neurologic manifestations of acid base derangements , electrolyte disorders, and endocrine crises.

Part I: EEG and neurological signs during the first year after cardiopulmonary resuscitation in patients subsequently regaining consciousness. The use of this website is governed by the Chen R, Young GB. Acute toxic-metabolic encephalopathy (TME), which encompasses delirium and the acute confusional state, is an acute condition of global cerebral dysfunction in the absence of primary structural brain disease [ ]. The two most common life-threatening complications of diabetes mellitus include diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar syndrome (HHS). While DKA is characterized by severe hyperglycemia, the presence of ketoacidosis without hyperglycemia in an alcoholic patient is virtually diagnostic of alcoholic ketoacidosis. Confusion is clinically defined as the inability to maintain a coherent stream of thought or action. These high levels occur because of a shift of potassium from the intracellular to the extracellular space due to acidemia, insulin deficiency, and hypertonicity. DKA is reported to be responsible for more than 100,000 hospital admissions per year in the United States and accounts for 4–9% of all hospital discharge summaries among patients with diabetes. Six-month neuropsychological outcome of medical intensive care unit patients. UpToDate synthesizes the most recent medical information into evidence-based practical recommendations that healthcare professionals trust to make the right point-of-care decisions.

An altered level of consciousness is any measure of arousal other than normal. Level of consciousness (LOC) is a measurement of a person's arousability and ...

In: Baillere's Clinical Neurology, Bolton CF, Young GB (Eds), Balliere Tindall, London p. DKA is the most common cause of death in children and adolescents with type 1 diabetes and accounts for half of all deaths in diabetic patients 25,000 mm or the presence of >10% neutrophil bands is seldom seen in the absence of bacterial infection. Similarly, the admission serum phosphate level may be normal or elevated because of metabolic acidosis. In: Management of the Acutely Ill Neurological Patient, Grotta, J (Ed) (Eds), Churchill Livingstone, New York Vol 1993, p. These high levels occur because of a shift of potassium from the intracellular to the extracellular space due to acidemia, insulin deficiency, and hypertonicity.

Acidosis: the prime determinant of depressed sensorium in diabetic ketoacidosis. The admission serum potassium concentration is usually elevated in patients with DKA. Deep coma and diffuse white matter abnormalities caused by sepsis-associated encephalopathy. Extreme hypertriglyceridemia, which may be present during DKA due to impaired lipoprotein lipase activity, may cause lipemic serum with spurious lowering of serum glucose (pseudonormoglycemia) in laboratories still using volumetric testing or dilution of samples with ion-specific electrodes. In addition, normal blood flow, normal temperature, normal osmolality, and physiologic pH are required for optimal central nervous system function [ ].

In: Young, GB, Ropper, AH, Bolton, CF, (Eds), Coma and Impaired Consciousness, McGraw-Hill, 1998. Mortality rates are 2–5% for DKA and 15% for HHS, and mortality is usually a consequence of the underlying precipitating cause(s) rather than a result of the metabolic changes of hyperglycemia. Most TME is reversible, making prompt recognition and treatment important. Many of these adult patients with DKA were classified as having type 2 diabetes because 29% of patients were obese, had measurable insulin secretion, and had a low prevalence of autoimmune markers of β-cell destruction. Neurologic manifestations of diabetic comas: correlation with biochemical alterations in the brain. The two most common life-threatening complications of diabetes mellitus include diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar syndrome (HHS).

In a recent series, the mean serum potassium in patients with DKA and those with HHS was 5. Acute toxic-metabolic encephalopathy (TME), which encompasses delirium and the acute confusional state, is an acute condition of global cerebral dysfunction in the absence of primary structural brain disease [ ]. Although there are important differences in their pathogenesis, the basic underlying mechanism for both disorders is a reduction in the net effective concentration of circulating insulin coupled with a concomitant elevation of counterregulatory hormones (glucagon, catecholamines, cortisol, and growth hormone).
